Time evolution of temperature, EM, and thermal energy of the flaring plasma derived from STIX, GOES, and AIA data for the B6 flare on 7 June 2020 (top panels). For the thermal energies, upper (dashed lines) and lower (solid lines) estimates using different flare volumes are shown. Evolution of the nonthermal energy and parameters from the thick target fit to the STIX spectra during the flare impulsive phase (bottom panels).
